To all whom it may concern:

Be itkuown that I, FREDRIGK HILDE- ,BRAN'D'L of the city, county, and Statev of New York, have invented a new and Improved Petroleum V(looking Stoveof which the following is a specication:

In Vthe accompanying drawing, Figure l represents a vertical transverse section ou line c c, Fig. 2, oi' my improvedpetroleum cookingstove; and Fig. 2, a bottom view ot' the same, with part of the bottom removed, to show interior construction.

Similar letters of reference indicate corresponding parts.

The invention relates to improvements in the burner of lamp for petroleum cookingstoves, by which the oil vapors are conducted from the interior of the oil-reservoir to the flame for complete combustion, and in which the spur-wheels for operating the wicks are arranged at the interior of the reservoir, so as to present a smooth top surface, which has a better appearance, and may be kept clean with greater ease.

rlhe invention consists of an oil-reservoir, whose side and 'top part are made of one piece of sheet metal, with a raised annular cenrer part, that communicates bysmall perforations, anda cylindrical conducting-tube, perforated at the top with the upper part of the burner. The burner is oi' circular shape, and provided between the wicksection with doubleradialpartitions,formingchannels,through which the oil vapors are conducted into the flame. The lowerpart of these channels communicates, by conical openings covered with wire-gauze, with the interior ot' the reservoir. The spur-wheels for operating the wicks are placed below the top ot' the oi1-reservoir, and

inserted and taken out through side openings and supportingplates, and protected against leaking by stem-inclosing tubes. The lower part of the burner is kept cool by an air-chamber formed by a cylindrical or conical tube, that is open at the lower part and perforated at the upper part. Y

v In the drawing, A represents the oil-reservoir or bowl of my improved lamp for petroleum cooking-stoves, which is placed on suitable feet to give ready access of air to the circular burner B, that extends through the Specification forming part of Letters Patent No. 184,078, dated November 7.', 1876; application filed y september 30,1576. I

central open part of,` the reservoir. The side wall and top part of the reservoir. are stamped or spunout of one piece oi' sheet metal, whichl is fitted by a raised annular part or molding, C, around the burner B. The raised part U is of conical or curved shape, and arranged for the twofold purpose of providing a funnelshaped space for ycollecting and conducting the oil vapors in upward direction Vto the burner, andalso for the purpose tot placing the wick-operating parts directly below the top part of the reservoir Vinstead of above the same, the raised molding providing the required space forthe spur-wheels. A cylin-v dricaltnbe, B', extends around the burner, leaving an'annular space, through which the oil vapors may pass up. The vapors enter to the tube B by small holes a of the quadrantal molding, and are drawn upward to the flame by top aperture b of tub'ew'B' and draft-holes b at the side of the same. The vapors are thereby continually fed under admixture` of air to the llame, so as to be entirely consumed without creating any obnoxious odors. The burner B is arranged with radial partitions d, for the purpose of admitting the use of the common flat wicks. The partitions d serve to guide the wicks, and form, also, by arranging two partitions between adjoining wicks, narrow channels dl, which are extended downward into the reservoir A, and communicate,

by openings d2 and conical mouths e, with the upper part of the reservoir. The conical mouths e are arranged just below the raised molding C, and provided with wire-gauze, to 'y prevent any possible danger of explosion.

The vapors are continually drawn upward by Vthe ame and consumed at the' upper end of the partition-channels, so that a dame without break is produced, as the burning vapors fill up the small gaps between the wicks. The operating stems or rods f of the spur-wheels D, that raise and lower the wicks, turn in bearings f1, immediately below the top of the reservoir, andalso in guide-tubes f2, that extend from the side wall of the reservoir to a point near the first spurwhee'l. The tubes f2 are secured to plates f3, that are soldered to the outside of the reservoir, of such size as to close side holes of the same, through which at any time, by removing the closing-plates, the

spur-wheels may beftaken out for repairs'. The tubes f2 extend a short distance to the outside of theA reservoir and prevent any leaking of oil. outer ends of the rods f serve to turn them for adjusting the Wicks. Y, 4 p y .Y ,y

rlhe advantage of arranging the Wick-operating parts at the inside of the reservoir, but so as to provide ready access for repairs, consists in the fact that the topv part is thereby perfectly smooth, Without obstructingparts in which oil, dirt, androther impurities may collect. This I consider an ,essential'point of my lamp, as the same can therebybe kept always neat-and clean Without anytrouble.

For the purpose of keeping the lower part of the burner or wick-tube in cool state, a conical or cylindrical tube, E, is arranged at the interior lower part of the burner B, and eX- tended to the height towhich the same is Within the reservoir. The tube E is open at the lower part, and attached to the burner at the top, Where suitablesideholes'gkeep up a continuous circulation of air between the' bowl A, molding C, and tube B constructedv Suitable hand-Wheels at the y tially as set forth.

in one piece, and varranged with respect to the burner, as shown and described.

2. The combination of annular raised part C, by exit-holes a, with a burner surrounding tube B, provided Withy vapor-issuing top openings b and. side draft-holes...b,-substantia1ly as specified.

3. The circular burner B, provided with double partitions between Wick-sections, -to form channels for escape of oil vapors, substantially as described.

Aelf. The combinationv of` double` partitions and vapor channels of the burner with lower 'apertures and conical mouths, covered by Wiregauze, to draw up the oilvapors to obviate dagger of explosion, substantially as specilie 5.'The combination of the Wick-'operating rods or, stems f withV the guide-tubes f2, ap plied to closing-plates f3 of the reservoir, to prevent leaking of oil, as described.

6. '.lvhe combination of the spur-wheels and lstems with the guide-tubes f2, closing-plates f 3, and recesses of reservoir, to admit taking `out`of wick-raising parts for repairs, substan- FREDRIGK HILDEBIRANDT.V`
